Comparing Auth providers (Supabase, Firebase, Clerk, Auth.js, Ory and others)
Zsolt Ero · Hyperknot blog Free Intermediate
Once you have decided to buy auth, this independent hands on comparison helps you actually pick one. It weighs developer experience, pricing at scale, and lock in across the exact providers named in the question, without being a vendor pitch. Use it to shortlist before you commit an afternoon to any single integration.
- Providers differ most on developer experience, pricing past the free tier, and exit cost
- Free tiers cover the whole early stage, so cost at scale is a later problem
- Lock in is real, so weigh how hard it would be to move off later
